Origami Design Secrets 2nd ed

The magnum opus of one of the world’s leading origami artists, the second edition of Origami Design Secrets reveals the underlying concepts of origami and how to create original origami designs. Containing step-by-step instructions for 26 models, this book is not just an origami cookbook or list of instructions―it introduces the fundamental building blocks of origami, building up to advanced methods such as the combination of uniaxial bases, the circle/river method, and tree theory. With corrections and improved illustrations, this new expanded edition also covers uniaxial box pleating, introduces the new design technique of hex pleating, and describes methods of generalizing polygon packing to arbitrary angles.

With coverage spanning the foundations of origami construction and advanced methods using both paper and pencil and custom-built free software, Origami Design Secrets helps readers cultivate the intuition and skills necessary to develop their own designs. It takes them beyond merely following a recipe to crafting a work of art.

Notes about the 2nd edition:
Even you already own the first edition, you may consider investing in the new edition. It has some major changes (extending the original book by a whooping close to 200 pages!), which include:

* Updates and corrections throughout the book.
* 4 new models: Dancing Crane, Silverfish, Roosevelt Elk & Organist. All previously published in other publications, but not always easy to find.
* More details about folding the koi's scales.
* 12 complex insect/arachnid crease-patterns added.
* The illustrations and diagrams' color-scheme has been modified for clarity.
* An expanded Box-pleating chapter, including uniaxial box-pleating methods.
* A new chapter on polygon packing.
* If you're interested in the mathematical algorithms behind the methods described, keep your first edition as this section has been cut from the new one.
